MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF file was flagged by a machine learning classifier as malicious. Static analysis revealed a large number of embedded links, forming a link farm. The primary heuristic indicates a 'PDF_SEO_LINK_FARM' with 23 external links, predominantly hosted on 'loaminoo.linkpc.net'. While the document body is unreadable, the structure and link farm suggest a traffic-driving or content-distribution scheme rather than direct exploitation.

Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
